To solve such questions, you must have the knowledge about Trigonometric Ratios of Compound Angles as you will need them to open the starting of the solution. Similarly, you will also require the basic knowledge of algebraic expressions cause whatever you will solve here is based on algebra. Let me give you the formula of compound angles so that you can understand them easily.


Now that you know the above mentioned formulas, you can start solving this question without even seeing the solution that I have mentioned above.
